Wheel offset for X3MC?

I am looking at aftermarket rims in 20x9 for a square winter setup on my pending X3MC.

Most sites dont have 2020 models. Can anyone confirm what offset is required and what width range 255/45/20 Scorpion Winters will work with?

Thanks!

The non comp X3/4 uses 9 x 20 with a 28mm offset with a 255/45 tyre, I use willtheyfit.com to check alternative wheel widths and offsets

This is great, thank you.

Looks like as long as I am within +/- 3mm it wont be much difference.

Are the wheels the same on the non comp and just the tire size is staggered? I thought the wheels were different sizes front and back?

Thanks!

Have you noticed the wheels sitting more in with the increase in offset?

Why not 265 or 275 instead of 255 curious?

Thanks for the pics. From my research (I am a noob at wheels) it seem that as you increase offset the wheels move further in the well and as you decrease it they move outward.

Yours do look a little pushed in but not sure how that compares to the OEM wheels. As people are getting spacers to push them out I suspect they are tucked in from factory?

I can't speak for DC F97, but my intention is to get more winter traction (narrower tires are better in the snow).

I doubt 10 or 20 mm would make that much of a difference though.

Agreed. Traction is key!
